Recognizing the Anatomical Layer of the Skin and Its Supporting Nutrients

Recognizing the Anatomical Layer of the Skin and Its Supporting Nutrients

Not as simple as it seems, the anatomy of human skin consists of several layers with their respective functions. The skin is one of the largest organs in the human body that covers almost the entire body surface. The skin has various benefits, such as protecting muscles, bones and internal organs, and protecting the body from germs, excessive fluid loss, and maintaining stable body temperature.

Dynamic Organs

Although it is rarely realized, the skin is a dynamic organ that continuously changes as long as a person lives. The layer that is on the inside will replace the entire outer layer without realizing it. The skin thickness of each person is different because it depends on gender, age, and also other factors. Men's skin is thicker than a woman's. Children's skin is thinner than that of adults.

Here are three layers of skin on the human body, starting with the outermost layer:


The epidermal layer has no blood vessels. Nutrient supply and disposal are obtained from deeper layers, namely the dermis. This supply is obtained through special channels that limit the epidermis and dermis. The epidermis itself consists of several layers, namely keratinocytes, melanocytes, Langerhans cells, and Merkel cells.

The thickness of the keratinocyte layer ranges from about 15-100 cells depending on the location of the skin and serves as the main protective layer of the external environment. Meanwhile, melanocytes have the function of producing pigments and melanin which will absorb energy from sunlight and protect the skin from UV radiation. Langerhans cells are produced by the bone marrow which functions as a protector of foreign substances. Then these cells are processed into smaller ones, before rolling it into the immune system in lymphocytes. Then, there are Merkel cells that function to make the skin sensitive to touch.


The dermis, as part of skin anatomy, has the main function of supporting the epidermis with a more complex structure. The structure includes the capillary blood vessels, elastic fibers, reticular fibers, and collagen fibers. In addition, the dermis also contains larger blood vessels along with nerve endings, lymphatic systems, fibroblasts, mastocytes, and others.

The dermis plays an important role in skin flexibility and maintains excellent skin condition.


The hypodermis is under the dermis layer and functions to attach the skin to the muscles or bones and supply blood vessels and nerves. Hypodermis itself is actually no longer part of the skin layer. In this layer, there is a lot of fat that will become a cushion and body heat insulation.

Supporting Nutrition

The skin needs nutrients to keep functioning optimally. Studies conducted confirm, changes in nutritional intake in a person can affect skin conditions.

So, what nutrients can support the skin? The content of vitamin A will help the formation of keratin in the outermost layer of the skin, reduce the production of sebum or natural skin oil, overcome skin damage due to exposure to UV light, and also improve cellulite conditions.

Meanwhile, vitamin C as an antioxidant will help collagen synthesis and protect the skin from UV exposure. Likewise, Vitamin E which helps the skin face oxidative damage and protect it from sun exposure. Then, vitamin D will help the immune system and other skin repair processes.

To control damage to the skin caused by free radicals, you can include some foods that contain antioxidants in your daily menu. Many types of fruits and vegetables are rich in antioxidants, for example, strawberries, blueberries, spinach, all kinds of peppers. Omega-3 fatty acids are also important to keep the outer layer of the skin strong. You can get this content from salmon, sardines, and walnuts.

Maintaining the health of each layer in the skin anatomy can be done through supporting nutrients. If necessary, avoid direct sunlight and use protective products. Consult a doctor, if there is a skin disorder.
